The length of `list` is 10, but the `max_results`'s value is `15`.

And, of course, the total count is `23`, which means as for the 1st page, it should be `15` items.

Start by reproducing the request against the search API endpoint with max_results=15 and inspect how results and list are generated. The fix is done when the first page returns up to 15 items when at least 15 matches exist, while results still reports the total count.

Written by the indexing model from the issue text.
